Croatia and the World Cup is a great example of what's possible when you believe in yourself. I've watched every Croatia match during the World Cup (even during the Group Stage), and one thing that really impressed me was their conditioning. Those guys are in fantastic shape. Even when their matches go into extra time, they don't put in substitutes. (and that's happened 3-4 times now!) So... one thing that I'd add to your post is that preparation is key. When you want to achieve something, you also have to put in the hard work. Anyway, I'll be rooting for Croatia on Sunday. Let's see if they can pull off one more miracle...
